Help you how?
Hosts have no control over what BNB does.
Unfortunately it sounds like you may have ruahed into hosting without taking the time to understand how BNB worked. You may have been right to have concerns, but you could have called BNB to discuss and/or checked out the implications of cancelling.
You then waited two weeks before contacting BNB about the penalties.
Don't worry too much about Superhost status. Concentrate on having lovely photo's, a great description, providing fantastic customer service and hopefully you will get fab reviews and ratings from your guest - this will be much more important for potenital guests than a superhost status.
